[0002] At present, the folding box houses on the market are mainly divided into waistline folding box houses and whole-board folding box houses, and the general specifications are about 3m×6m×3m (width×length×height). Folding box houses are more and more accepted by the market due to advantages such as low transportation cost, high loading, unloading and assembly efficiency, small secondary disassembly and assembly loss, and small storage site occupation.

[0003] At present, after the whole-board folding box house on the market is folded, an independent packing corner post is required to support the top frame. Among them, the method of using an independent packing corner post to support the top frame only solves the transportation problem of the product (whole-board folding box house) from the factory to the destination; the subsequent secondary disassembly and transportation problem has not been solved, because customers will not keep the packing corner posts during the use of the whole-board folding box house. When secondary disassembly is required, customers need to pay an additional fee for the packing corner posts.

The detachable connection can be achieved by an articulated mechanism (such as a hinge) or by a bolt connection. After the side wall 7 is removed, the two side walls 7 are turned / laid down towards each other and then placed on the bottom plate of the bottom frame 2.

[0082] In one embodiment, the high platform of the first joint step of the column 8 is rotatably connected to the high platform of the bearing table of the pedestal bottom corner member 3 through a rotating shaft 31. When the folding container house needs to be folded and stored, the column 8 rotates and turns towards the bottom plate of the bottom frame 2 (i.e., towards each other) together with the front wall 5 or the rear wall 6 around the rotating shaft 31. When the side wall 7 that has been turned / laid down is placed on the bottom plate, the front wall 5 and the rear wall 6 are directly placed on the side wall 7. Preferably, the rotating shaft 31 and the rotating shaft hole 15 are provided at the inner top corner of the high platform body of the pedestal bottom corner member 3, and the height of the high platform body is matched with the overall height of the two side walls 7 stacked on the surface of the bottom plate, so that the overturned front wall 5 or rear wall 6 can be stacked (horizontally) on the two side walls 7.

[0083] In one embodiment, Figure 9 is an isometric view of the lower end of the column 8, Figure 10 is an exploded view of the lower end of the column 8; the column body 28 has a column lower closing plate 30 and a column lower connecting plate 29, and the two form the first joint step. A rotating shaft 31 is provided on the high platform body of the first joint step to form a rotating connection with the rotating shaft hole 15. In one embodiment, Figure 11 is an isometric view of the upper end of the column 8, Figure 12 is an exploded view of the upper end of the column 8; the column body 28 has a column upper closing plate 32 and a column upper connecting plate 33, and the two form the second joint step. A nut 41 is embedded in the column upper connecting plate 33 of the column 8 for bolt installation during the assembly of the folding container house, such as Figure 11 、 12 . A pulley shaft connection hole 34 is provided on the high platform body of the second joint step for forming a rotating connection with the pulley mechanism 36, such as Figure 21 . Preferably, the column 8 can be made of rectangular tubes (such as Figures 9 - 13 ), or can be made by bending a steel plate (such as Figure 19 、 20 ); the column body 28, the column lower connecting plate 29, the column lower closing plate 30, the rotating shaft 31, the column upper closing plate 32, and the column upper connecting plate 33 are welded together to form the column 8.

[0084] In one embodiment, the second engaging step of the column 8 forms a sliding connection with the top frame longitudinal beam 39 of the top frame beam through the pulley mechanism 36, and a slide rail 37 is formed inside the top frame longitudinal beam 39. The pulley mechanism 36 includes: a pulley pair 38 and a connecting member; wherein, the pulley pair 38 has a pair of pulleys and an axle connected between the pair of pulleys; the pulleys are arranged inside the slide rail 37 and are used for moving along the length direction of the top frame longitudinal beam 39; the first end of the connecting member is rotatably connected to the axle, and the second end is provided with a rotating sleeve, and the rotating sleeve is sleeved on the pulley shaft 35 inside the high platform of the second engaging step, as Figure 21 . The length of the connecting member is matched with the top frame longitudinal beam 39 and the high platform of the second engaging step. When the front wall 5 and the rear wall 6 are overturned and the top frame longitudinal beam 39 is laid flat on the overturned column 8, the connecting member is used to keep the pulley pair 38 continuously connected to the top frame longitudinal beam 39 and not separated from the slide rail 37; at this time, the folding container house is in a folded storage state; the purpose of the pulley mechanism 36 always keeping connected to the top frame longitudinal beam 39 is that when the top frame 1 is lifted to unfold the folding container house, it is convenient for the pulley mechanism 36 to pull the overturned column 8 to rotate around the rotating shaft 31 and stand up to achieve the unfolding effect.

[0085] In one embodiment, when the high platform of the bearing step supports the high platform of the supporting step, a storage space is formed between the top frame 1 and the bottom frame 2, and the storage space is used for storing the bottom plate, the overturned front wall 5 and the rear wall 6. Wherein, the length of the side wall 7 is greater than or equal to the sum of the heights of the front wall 5 and the rear wall 6; preferably, half of the length of the side wall is greater than or equal to the height of the front wall 5 or the rear wall 6, and more preferably, the heights of the front wall 5 and the rear wall 6 are equal.

[0086] The disassembly and assembly of the folding container house are introduced as follows:

[0087] Figure 2 The figure shows the folding container house in the unfolded state. After unfolding, the bearing type apex member 4 of the top frame 1 is connected to the bearing type bottom corner member 3 on the bottom frame 2 through the columns 8 on both sides of the front wall 5 and the rear wall 6 and is supported by the bearing type bottom corner member 3.

[0088] Figure 14 The figure shows the schematic diagram of the unfolding / folding process of the folding container house. When the lifting equipment pulls up or puts down the top frame 1, the front wall 5 and the rear wall 6 are unfolded outward (at this time, the column 8 flips and gradually stands up to achieve unfolding) or folded inward (at this time, the column 8 flips and gradually falls down) around the rotating shaft 31 through the pulley mechanism 36 connected to the top frame 1 to achieve storage.

[0089] Among them, the lifting hole 21 of the top corner piece is located at the end of the folding container house; on the side where the end of the folding container house is located on the pedestal-type top corner piece 4, there is a top corner piece wing, and the function of the top corner piece wing is to weld and fix the end beam of the top frame. A limiting edge 40 is reserved on the high platform of the pedestal-type top corner piece 4 near the edge of the top corner piece wing, and the limiting edge 40 is used to limit the upright column 8. The protruding height of the limiting edge 40 is preferably the same as the thickness of the top corner piece connecting plate 23. Specifically, the limiting edge 40 restricts the excessive turning of the upright column 8 when the upright column 8 turns over and gradually stands up, so that the second end of the upright column 8 is separated from the top frame 1. In other words, when the top frame 1 is pulled up, the front wall 5 and the rear wall 6 turn over and gradually stand up to achieve unfolding. The second end of the upright column 8 is likely to pop out of the top frame 1. At this time, the limiting edge 40 will block the second end of the upright column 8 to play a limiting role and prevent the second end of the upright column 8 from separating from the top frame 1, as Figure 18 .

[0090] Among them, the pedestal-type bottom corner piece 3 is provided with a bottom corner piece wing, and the bottom corner piece wing is arranged on the pedestal-type bottom corner piece 3 and on the side where the end of the folding container house is located. Figures 3 - 5 In [description], the installation height of the middle sealing plate 12 of the bottom corner piece is significantly lower than that of the bottom corner piece wing, and the function is to facilitate drainage and prevent rainwater from entering the interior of the folding container house; the function of the bottom corner piece wing is to weld and fix the end beam of the bottom frame and limit the bottom plate, as Figure 17 .

[0091] Figure 1 As shown in the figure, it is a folding container house in the form of an integral plate in the folded and stored state. The top frame 1 is supported on the pedestal-type bottom corner piece 3 of the bottom frame 2 through the pedestal-type top corner piece 4, and all the weights are borne by the pedestal-type bottom corner piece 3. The front wall 5, the rear wall 6 and the side walls 7 will not be squeezed.

[0092] It can be seen that for the folding container house of the present invention, in the folded state, the top frame 1 is supported on the pedestal-type bottom corner piece 3 of the bottom frame 2 by using the pedestal-type top corner piece 4 of the top frame 1, and all the weights are borne by the pedestal-type bottom corner piece 3, and there is no need to additionally set up packing corner columns. In the unfolded state of the folding container house, the top frame 1 is connected to the pedestal-type bottom corner piece 3 through the upright column 8 by using the pedestal-type top corner piece 4; in this way, the bottom frame 2 supports the top frame 1 and forms an unfolded folding container house, showing the attributes of a house.

[0093] The folding container house of the present invention has the following advantages:

[0094] 1. Using pedestal-type corner pieces with a bearing function, such as the pedestal-type bottom corner piece 3 and the pedestal-type top corner piece 4, enables the folding container house to bear the weight of the top frame 1 by the pedestal-type corner pieces after folding, and the front wall 5, the rear wall 6 and the side walls 7 are received between the top frame 1 and the bottom frame 2, so as to avoid being squeezed by the front wall 5, the rear wall 6 and the side walls 7, and reduce the risk of the wall panels being scratched and deformed during transportation;

[0095] 2. The pedestal bottom corner piece 3 is connected to the bottom frame 2, and the pedestal top corner piece 4 is connected to the top frame 1, so that there is no need to additionally add packing corner columns during the disassembly and assembly process of the folding container house in the future, avoiding the situation that the packing corner columns are not saved and easily lost after the folding container house is unfolded, saving costs for users;

[0096] 3. The hidden structure of the rotating shaft 31 replaces the hinge method. The height of the rotating shaft 31 corresponds to the positions of the front wall 5 and the rear wall 6 after folding (the height of the rotating shaft 31 is greater than or equal to the plane position where the front wall 5 and the rear wall 6 are located after folding), so as to ensure that the front wall 5 and the rear wall 6 are folded and laid flat on the side wall 7;

[0097] 4. By setting the recessed bolt connection method, the bolts are more convenient to install outdoors than indoors, and the problem that the two boxes cannot be closely assembled due to the exposed bolts is solved. Two or more folding container houses are installed side by side or overlapped to form a folding container house unit.
